UN chief concerned over escalation of violence in Gaza
United Nations, July 22 : United Nations Secretary-General Antonio Guterres has expressed his "grave concern" over the dangerous escalation of violence in Gaza and southern Israel.
"I deeply regret the loss of life. It is imperative that all sides urgently step back from the brink of another devastating conflict," the Secretary-General said in a statement on Saturday, Xinhua news agency reported.
"I call on Hamas and other Palestinian militants to cease the launching of rockets and incendiary kites and provocations along the fence. And Israel must exercise restraint to avoid further inflaming the situation," said the UN chief.
"I encourage all to engage with the UN, and particularly my special coordinator, and work to find a way out of this dangerous situation. Any further escalation will endanger the lives of Palestinians and Israelis alike, deepen the humanitarian catastrophe in Gaza and undermine current efforts to improve livelihoods and support the return of the Palestinian Authority to Gaza," he noted.
Four Palestinians were killed and some 210 Palestinians wounded on Friday during fierce fighting between Israel and Hamas, the most serious one in the Hamas-ruled Gaza Strip since the 2014 Israel-Gaza conflict that killed thousands.
The attack began after an Israeli soldier was killed during operational activity near the southern Gaza Strip on Friday. The soldier was the first one to be shot dead by Palestinian fighters since 2014, the Israel Defense Forces said.

Groundwater depletion causes Earth's axis to shift by 31.5 inches: Study
A recent study has uncovered a significant impact of human activity on the planet: Earth's axis has shifted by 31.5 inches (nearly 80 centimeters) due to extensive groundwater extraction. Published in the journal Geophysical Research Letters, the research highlights how large-scale pumping of groundwater has changed the distribution of Earth's mass, affecting its rotation and contributing to sea-level rise. The shift in Earth's tilt is linked to a sea-level increase of 0.24 inches, according to Popular Mechanics.
Lead researcher Ki-Weon Seo, a geophysicist at Seoul National University, explained that among climate-related factors, the redistribution of groundwater has had the most significant effect on the movement of Earth's rotational pole. The planet's tilt, or axial precession, is influenced by changes in mass distribution. As glaciers and polar ice sheets in Greenland and Antarctica melt, water migrates towards the equator, shifting the planet's balance—a phenomenon comparable to how a figure skater’s spin changes when they alter their body position.
The study examined data from 1993 to 2010, revealing that approximately 2,150 gigatons of groundwater were pumped out during this time, largely for agricultural and human consumption. This large-scale extraction has contributed to a shift in Earth's axis of about 31.5 inches.
Groundwater, which is water stored underground in soil and rock, plays a crucial role in the hydrological cycle. It originates from precipitation that seeps into the earth, replenishing natural aquifers. These aquifers are vital freshwater resources, supporting drinking water supplies, agriculture, and industry. The availability and quality of groundwater depend on natural factors like recharge rates and human activity.
While the 31.5-inch shift in Earth's axis might seem minor, the consequences could be far-reaching over geological timescales. Changes in water distribution can lead to varying sea-level changes across regions, affecting coastal areas differently. Additionally, shifts in Earth's tilt can influence its internal systems, such as the magnetic field, which acts as a shield against harmful solar radiation.
